DRIVING SUPPORT APPARATUS FOR VEHICLE
First Claim
1. A driving support apparatus for vehicle for recognizing conditions surrounding the vehicle and providing driving support to a driver of the vehicle, comprising:
- an obstacle determination unit configured to detect an obstacle existing outside of the vehicle, and to determine whether said obstacle is a first-type obstacle that is visually recognizable by the driver, or a second-type obstacle that is visually unrecognizable by the driver; and
a driving support setting unit configured to set driving support for avoiding a collision with said obstacle, wherein a collision risk of the second-type obstacle is evaluated as being higher than a collision risk of the first-type obstacle.

Abstract
The object of the invention is to provide driving support with appropriate timing for both obstacles that can be visually recognized by the driver of a vehicle and obstacles that are visually unrecognizable to the driver. When an obstacle is detected, whether the obstacle is a first-type obstacle that is visually recognizable to the driver of a vehicle or a second-type obstacle that is visually unrecognizable to the driver is determined (S2), the collision risk (base value) for each kind of obstacle is modified and adjusted such that the collision risk of a second-type obstacle is larger than the collision risk of a first-type obstacle (S3). In addition, the collision risk R2 of a second-type obstacle is compared with a threshold value Rc, and when R2≧Rc, a warning is output for the second-type obstacle (S5). Moreover, when R2<Rc, the collision risk RI of a first-type obstacle is compared with a threshold value Rcc, and when R1≧Rcc, it is determined that there is danger of a collision, and auto braking or evasive steering (S7) are performed. By doing so driving support is performed with appropriate timing for both obstacles that are visually recognizable to the driver of a vehicle and obstacles that are visually unrecognizable to the drive, and safety is maintained.
